TYPE-WRITING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 678,552, dated July 16, 1901.

Application filed November 14, 189i?- Seria1N0.736,920. (N model.)

To all whom it may concern: Be it known that I, LOUIS P. DISS, a citize of the United States, and a resident of Ilion, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Type-IVriting Machines, of which the following is a specification.

My invention relates to papercarriages of type-writing machines; audits object is to.

provide improved means for indicating the position of the carriage.

The improvement is particularly adapted for those machines in which the carriage is provided with an escapement-rack that meshes with a pinion. In the preferred form of the invention I provide the rack with a letter-space scale and fix upon the pinion a series of indexes, so that the indexes revolve together with the pinion as the rack travels 2o endwise and so that when each index reaches its highest rotative point it stands in register with a graduation upon the rack.

The preferred form of the in vention is illustrated in the accompanying drawings, form- 2 5 ing part of this specification, in which- Figure 1 is a front view of the top portion of a Remington No. 0 type-writing machine, the carriage being turned up to bring the lower surface of the platen into view and the top plate and type-ring being shown in section. Fig. 2 is a vertical longitudinal central sectional view of the said machine, but with the carriage turned down. Fig. 3 is an enlarged front elevation, including a fragment of the 3 5 carriage-rack, a scale thereon, and an indexwheel. Fig. 4 is a plan of the parts shown at Fig.3, and Fig. 5 is an elevation of a modified index-wheel.

The same numerals of reference will be used to designate the same parts in the different views.

1 designates a base, 2 corner-posts, and 3 a top plate or type-ring, which is secured upon the corner-posts, the whole forming a framework for supporting the various portions of the type-writing mechanism.

4 is a carriage provided with guide-rolls 5, which run upon a rail 6, secured to posts 7, rising from the top plate. The carriage is provided with a rearwardly-extending arm 8, having at its back end a yoke,which engages a sleeve 9, loosely mounted upon a rail 10,

the latter being secured to post 11, also rising from the top plate.

A cylindrical platen 12 is secured upon a shaft 13, the latter being provided with handwheels 14 and being journaled in the end bars 15 of aplaten-frame, the remainder of the frame comprisingafront bar16 andacylindri- 'cal rearbar 17. V The platen-frame is pivoted at 18 to a pair of rocker-arms 19, which are pivoted at 20 to the carriage 4. The platenframe is provided with a grooved front roll 2'l,(omitted from Fig. 1,) Whichrides upon a rail 22, suitably supported upon the top plate. Upon this rail is mounted a pointer or an index 23, which cooperates with a scale 24, secured by means of arms 25 upon the front bar 16 of the platen-frame. The platen is provided with pressure-rollers 26, which work in openings 27,formedin a paper-guiding plate or apron 28, which is pivoted to the end bars 15 of the platen-frame bya shaft 29 and which bears upon its forward end a scale 30, which touches the platen and is used in positioning the paper thereon.

The carriage is given a tension toward the left by means of a spring-drum 31, to which is secured at one end a flexible strap 32, the

other end of which is suitably secured to the carriage. A pair of arms 33 is pivoted to the carriage at 34 and curve upwardly over the rail 6 and down in front thereof, and a horizontal rack 35 is secured to said arms by means of screws 33 passing through the rack and engaging said arms. Arranged below said rack and in mesh therewith is a pinion 36, which is fixed to the front end of a hori zontal shaft 37, which turns in a bracket 38, fixed upon the top plate. 7 At its rear end the 0 said shaft carries a backing-ratchet housed in a drum 39, and also an escapement-wheel 40. The rack may be swung up about the pivot 34 by means of a lever 41, which is pivoted to the platen-frame at 42 and is provided with 5 a finger-piece 43. Upon being thus released from the control .of the pinion and escapement devices the rack and carriage can be moved freely endwise in either direction.

44 and 45 are escapement-dogs working in the teeth of the escapement-wheel 40 and mounted upon a spring-pressed rocker 46, which turns upon an axis 47 and is provided with forward extensions 48, from which hang Y bar 53.

hooks 49, that carry a universal bar. 50, arranged beneath a series of key-levers 51, each of which is connected by a link 52 to a type- Upon the depression of any key the corresponding type-bar is operated and the universal bar 50 is depressed, thus drawing down arms 48 of the dog-rocker andcausingl the dogs 44 45 to move forwardly. Upon the release of the key the type recedes from the platen, the universal barand dog-rocker resume their normal positions, and the escapement-wheel advances one tooth, permitting the carriage to be moved a letter-space dlS- tance by the spring-barrel 31.

The hereinbefore-described mechanism is common in the Remington No. 6 type-writ-- ing machine.

I provide the rack 35 with suitable 1etter space graduations, preferably by fastening upon the rack a sheet-metal scale 54 bymeans of small screws 55, which engage threaded holes formed in the heads of the screws-33.

An ind ex-wheel 56 is rigidly secured to the pinion 36 by means of a screw 57, a collar 58'being disposed between the index-wheel and the pinion in order to position the index-wheelin front of the scale 54. The index-wheelprefl erably comprises a series of equidistant indexes or points 56, the uppermost one of which always registers with a graduation upon the scale 54. The said points are pref erably equal in number to the teeth ofthe pinion 36, and the rack-teeth arepreferably arranged at letter-space intervals. Rotative adjustment of the index-wheel relatively to the pinion is permitted by the screw 57. The index-wheel may be constructed in a variety of ways. For example, it may be made in the form of a circular disk, the face whereof may be provided with a series of radial graduations adapted to cooperate with the scale 54,

as shown at 56 Fig. 5.

hen the platen-frame is down in working dicate the position of the carriage. When the platen-frame is swung up, as at Fig.1, the platen-scale 30 is brought into view, and by reference thereto the operator can determine the position of any printed letter upon the paper, and upon referring to scale 54 and index-wheel 56 he can position the carriage at any desired point by moving the carriage until the desired graduation registers with the topmost index 56 of the star or index wheel. The graduations on scale 54 read from left to right, the same as those upon the platen-scale 30, and preferably the marks upon the scale 54 are directly below or in line with the corresponding marks upon the platen-scale 30, or, in other words, whenever the carriage is arrested by the escapement mechanism in position to receive another type-impression the corresponding graduations upon the two scales 30 and 54, as well asthe axis of the pinion 36, lie in the same vertical plane as the printing-center.

It will thus be seen that I have provided a simpl e,cheap, and efficient index which is adapted to be adj ustably supported by means of a single screw and which, owing to its solid and simple construction and arrangement, is not liable to become accidentally bent or moved out of true position. 7

It'is not essential that the index-wheel be secured 'to an escapement-wheel pinion or that itbe arranged in the same vertical plane as the printing-center so long as it is adapted to rotate during the letter-spacing movements of the carriage.

Inasmuch as the teeth of the pinion may correspond in number and position to the points of the star-wheel and at the cessation of each letter-space movement of the carriage one tooth of the pinion may stand vertically and in register with a graduation of the scale 54, it will therefore be understood that the said-pinion in itself maybe made to constitutea rotatory star-wheel or multiplicate index to cooperate with the said rack for notating the position of the paper-carriage while the latter is.in its upturned position and so that when the carriage is turned down the point previouslyselected for. the typeimpression may by the downward motion of the carriage be brought at once over the printing-center of the machine in order that the next impression may be made at the desired pointupon the paperwithout further adjustment. NVhile the pinion may thus serve the same purpose'as the star-wheel, nevertheless I prefer to use the separate rotatory device 56 in lieu thereof, for the reason that it may be made larger than the pinion and so that its points or graduations will reach or come nearer to the graduations upon the rack 54, and thus make it easier for the eye tonote the positionof the carriage. A further reason for preferring the star-wheel lies in'the fact that the points of the latter may be made'sharper than those of the teeth of thepinion, and hence register more clearly with the graduations of the scale than would the necessarily wider or more bluntteeth of the pinion.

It will also be noted that I have combined with platen-scale 30, rack 35, and pinion 36 ascale upon said rack whose graduations are in line with the scale 30 an d a rotatory pointer adaptedto cooperate with the scale on the rack, the pointer being arranged in a vertical plane passing through the axis of the pinion.

It will be seen that the scale 54 may be IIO readily secured to the carriage and that the tion with a platen-frame adapted to swing up to exhibit the writing, and with a suitable scale, as 30, arranged in proximity to the platen, of a companion scale, as 54, having graduations in line with those of scale 30, and adapted to be brought into view when the platen-frame is swung up, and a suitable rotatory index-wheel arranged upon the machine-frame and adapted to cooperate with the last-mentioned scale, whereby the platenframe may while swung up be positioned aocurately at any desired point in its travel.

2. In a type-writing machine, the combination of a carriage having a scale, a scale extending longitudinally of the carriage and corresponding with the first-mentioned scale, and a wheel arranged in proximity to the scale and having suitable points or graduations thereon adapted to cooperate with the scale to position the carriage, and means for rotating said wheel during the letter-space movements of the carriage.
